My invention relates to yarn-dyeing mechanism, and particularly to improved means for carrying yarn as commonly wound upon tubular spools during the dyeing operation; a main object being to provide for avoidin elongation and disarrangement of the woun yarn and enabling satisfactory Subsequent use. The invention consists in the improved construction hereinafter fully described in connection with the accompanying drawing illustrating a preferred embodiment of the complete invention, and is clearly defined in the subjoined claims.

Fig. 1 is asectional elevation showing my improved yarn carrying spindle in connection with a spool mounted thereon; the spindle being indicated in vertical'position' as when applied to an ordinary carrier of the horizontal type, and as adapted to receive a plurality of stacked spools which is frequently desired.

Fig. 2is' a cross-sectional view on the line 22 of Fig. l. t

The type of dyeing mechanism employed is immaterial to my invention, and I. have merely indicated in the drawing a carrier plateA to which any desired number of spindles may be secured with usual pump communication for forcing the dye liquid through theyarn spools mounted thereon; my invention being equally applicable to the horizontal or vertical cylinder type of carrier.

The yarn spool indicated comprises merely the usual perforated-wall tube B, of suitable material, on which the undyed yarn is Wound to desired size and form C, with projecting ends of the tube extending as indicated at b I) these spools being mounted upon the supporting spindles as stated, for the dye ing operation.

My improvements provide essentially for so supporting these spoolsupon the spindle as to maintain positive endwise pressure upon the wound yarn while subjecting the latter to the action of the forced circulation of dyeing liquid therethrough, and so prevent endwise spread and disarrangement of the yarn.

upon the perforated wall tube B, and further satisfactory use of the dyed product.

To these ends I employ a spool-supporting spindle 10 through which the dyeing liquid is distributed under pressure, to the spools mounted thereon, through a hollow screwhead 11 which serves to connect the "spindle to the horizontal plate or vertical wall A of the carrier employed; this spindle being preferably of-the longitudinallyfiuted type as shown, though the perforated tube type of spindle may be similarly used. Upon this spindle ll provide a pair of relatively adjustable yarn-compressing disc-faces between which the interposed spool is mounted, with the projecting ends b b of the spool tube B extending loosely into concentric annular recesses 17 of the disc hubs so that the wound yarn may be freely compressed endwise between the discs.

The drawing illustrates a construction in which the spindle 10 is lengthened so as to provide for mounting a plurality of spools thereon in stacked relation; but it will be readily understood that with a single spool the spindle may be made correspondingly shorter and the interposed adjustable discs shown at 15 16 omitted. As illustrated, the

disc 15 is conveniently made integral with the carrier-connecting hub 11 whereby it is fixed to the spindle 10; while the outer disc 16 is adjustably secured to the free end of the spindle so that it may be forcibly pressed against the adjacent end of wound yarn C; this being effected as shown by merely turning its ainteriorlyscrew-threaded hub 11 upon the screw-threaded end 10 of the spindle. When the spindle is arranged to receive only a single spool, the adjustable dis'c l6 will thus directly compress the wound yarn endwise between disc 16 and disc 15, the projecting opposite ends I) b of the spool tube B freely extending more or less into the annular hubrecesses 17, 17 as required to effect desired compression. When a plurality of spools are mounted upon a single spindle, as illustrated, a double disc, as 15 16*, having similar tube-receiving annular recesses 17, 1?, is simply interposed between adjacent spool ends so as to be freely movable upon the spindle 'by movement of the adjustable end disc 16, thus providing for uniformly compress ing the wound yarn on the several spools.

To provide for circulating the dyeing liquid in contact with the ends of wound yarn thus closely held in contact with the respective discs, I simply form the latter, as shown, with radiating grooves 15?) adapted to serve as liquid passageways. To enable compressing adjustment of the end disc 16 upon the s indle without causing objectionable rubbing action upon the yarn, I referably conub 11a to the nect the screw-threaded disc separately formed disc plate 16 so as to permit of its rotation independently of the latter, as illustrated; so that there will be no turning of the disc against the contacting yarn in effecting desired compression. It will be understood that this endwise compression of the wound yarn not only practically prevents endwise extension upon the tube B, but also avoids objectionable disarrangement of the windings, thereby adapting it for most satisfactory subsequent use; and that the preferred construction specifically set forth may be readily modified in detail without departing from the invention as defined in the claims.

What I claim is:

1. In yarn-dyeing mechanism comprising a spool carrier and perforated-tube yarn spools mountable thereon; mounting means for said spools each comprising a liquidcirculating spool-supporting spindle having a hollow.screw-head for connection thereof to the carrier, a. pair of liquid-circulating yarn-compressin discs relatively adjustable axially upon sai spindle and upon the projecting ends of the perforated-tube spools, and disc-adjusting means adapted to press said discs against the interposed wound yarn.

2. A mechanism as set forth in claim 1 in which the'spindle is lengthened so as to enable stacking of spools thereon, and is provided with additional reversely faced axially movable discs located between adjacent spools and adapted to be pressed against the interposed wound yarns.

3. In a mechanism as set forth in claim 1, a yarn-compressing disc having a hub formed with a central spindle opening'and with a concentric tube-receiving recess.

4. In a mechanism as set forth in claim 1,

a yarn-compressing disc having a separately 7 formed rotatably-engaged hub portion formed with a screw-threaded central opening and with a concentric tube-receiving recess.

In testimony whereof I afl ix my signature.

MAX THUS.
